Blockchain ICO ranking

1. bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

2. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

3. There are many. Zebra blockchain lp8362 has private channel

4. Blockchain exchange
you mean platform trading. Domestic illegal, international and mostly deceptive, you find the well-known ones. There is a special introction to blockchain network. Remember to be legal, otherwise you can't withdraw cash and it's useless to make money.

6.

STOSecurity Token Offeri‌&# 8204; "Security token issue". In terms of name, it is similar to ICO and IFO in concept, and it is a way of token issuance. The most prominent feature of STO is that the token issued has the property of securities, which is regulated by securities institutions (such as SEC) and relevant securities laws and regulations

ICO (abbreviated as initial coin offering) is an IPO concept derived from the stock market. It is the behavior of blockchain project to issue token for the first time and raise bitcoin, Ethereum and other common digital currencies

both ICO and sto are procts of digital capital. In the era of blockchain, they are not black or white. Eggs should not be put in the same basket. So how to invest? It depends on whether you want to be an egg maker or an egg seller

if you are an ordinary investor and register a digital wallet, you can buy and sell on major trading platforms such as currency / currency security; For project investors, they can issue their own currency to achieve more financing goals. At present, Singapore is the holy land for Asian blockchain to settle down, mainly because the local policy and atmosphere are very relaxed, and there is no need to pay tax to register a public non-profit foundation in Singapore to do overseas projects, The Inland Revenue Department of Singapore will not tax local capital injection and investment

registration process of Singapore Foundation: the ID cards of two registered directors and the company name are required for verification, and the registration can be carried out after the verification, which takes a total of 10-25 working days

because of the new technology&# 8204; Due to the particularity of the economic environment in Gabor, in the later period of the foundation, it is legal to carry out such actions as ICO and other currency transactions. Some friends in the blockchain instry know that to do ICO blockchain, they need to register in Singapore. In order to achieve more compliant operation in the later period, it is suggested that investors register in Singapore foundation as soon as possible for financing

7. Of course,
we are doing a lot of projects, and the coin circle is beginning to warm up. Sto is well publicized, but it is much more difficult to operate in practice than 1CO. Because the nature of its birth is securities, it needs to be regulated. Sto can't replace 1CO, so do it boldly

8. It is a new form of distributed artificial intelligence. 21, which goes beyond the traditional and conventional information verification paradigm that needs to rely on the center. We can query the history of each bitcoin transaction: a spends 80000 to B, so that all data changes or transaction items are recorded on a cloud system. Now suppose that Party A and Party B each have one million yuan in their custody. So. B turns 50000 to a, which records the user's ownership of bitcoin and the records and examples of all users' transactions of bitcoin. 3, and these data are shared by all bitcoin nodes, through the data block, three people of C, and add 80000 yuan in the name of B. Bitcoin's "account book" is called data blockchain, which replaces the current dependence of the Internet on the central server with data blocks and subtracts 50000 yuan from the name of B. the essence of data blockchain technology is decentralized and embedded in distributed data storage. If Party A spends 50000 yuan to Party B, Party C will add 50000 yuan to the account book, and all the funds of Party A and Party B will be kept by Party C. 4. The function of data blockchain is similar to that of C's account book. In addition, each capital transaction should be recorded by C, which theoretically realizes the self proof of data in data transmission: A, C is in the account book record, and C is in the account book record, which reces the establishment cost of global "credit". This kind of point-to-point verification will proce a "basic agreement". All the data blockchains on the network constitute the distributed network database system of bitcoin, subtracting 50000 yuan under the name of institute a, and adding 50000 yuan and 50000 yuan under the name of institute B. If a bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain, and the method of transmission and proof will establish a new interface and sharing interface for human brain intelligence and machine intelligence, minus the 80000 yuan in the name of institute a, recording the transaction record data on the whole bitcoin network Data blockchain is an important concept in bitcoin financial system. It's just that this "book of accounts" is made up of the mining records of every bitcoin miner on the Internet

9. Blockchain is technology, bitcoin is digital currency or electronic currency based on blockchain technology, and blockchain technology is the basic technology of all digital currencies. The two are complementary. ICO is the first time to issue currency, which is similar to IPO in stocks
